2cm双端平衡检波器设计

Design of the dual port balance detector of 2cm

设计一种2mm双端平衡检波器。检波器中采用了双端平衡结构,增加了带宽,提高了检波器的稳定性。通过软件仿真和实验数据分析,这种检波器的带宽为2GHz（14.5~16.5GHz）,在频带内检波灵敏度大于200mv/m W,起伏度小于1d B,电压驻波比小于2.5。这种检波器可以应用于2mm雷达接收系统的信号检测和稳幅器中。

This paper designs a dual port balance detector of 2cm.For increasing bandwidth and improving the stability of the detector,we use a dual port balance structure.Through simulation and analysis of experimental data,the bandwidth of the detector is 2GHz from 14.5GHz to 16.5GHz,and the detection sensitivity is more than 200mv/m W.The waviness is less than 1d B,and VSWR is less than 2.5.The detector is used in signal detection of 2cm radar receiving system and leveled device.
